Stress

It's happening again, this stress-related pain I get in my neck/shoulder on the right side.  Why?  I'm not really sure.  I've been stressed lately, for sure.  But why sometimes it goes to my neck and sometimes it doesn't I am not sure.  I think this time, though, I am going to get a massage.  Otherwise I could be out of work again for another day or more, and that's never good.  I need to learn better how to deal with the stress.
